Limonite rotary kiln is a machine for calcining, roasting, treating and sintering hematite ores. It is widely used in metallurgical, building materials, chemical and environmental industries. The plant can be used to process different types of iron ore, converting them into high quality iron ore products.
Model: Φ2.2x38m--Φ4.3x64m
Capacity: 120tpd-800tpd
Material: Limonite
Rotary kiln for limonite is mainly applied in building materials, metallurgy, chemicals, and the environmental protection sector. Also, it can be used in calcimine ore, concentrate, intermediates, etc. Because the production advantages of rotary kiln for limonite are gaining more energy and consuming less of it. So, it plays an important role in energy saving, environmental protection businesses, and cost reduction in small and medium-sized steel enterprises, coking enterprises, calcium carbide enterprises, and refractory industries.
Rotary kiln for limonite’s raw ore is taken out from depot and successively go through electronic belt measuring scale, belt conveyor, stable silo, lock damper and then be put into kiln tail.
After the mineral is put into a rotary kiln for limonite, firstly it is heated, mineral proceeds backward motion with the hot flue. Then, it is heated to a reduced temperature in the heating zone and put into the reduction zone.
Rotary kiln for limonite’s temperature of the flame center in the reduction zone of the limonite rotary kiln is about 1000 °C, and the temperature of the reduction zone is about 700 °C by which mineral turns into magnetite by reacting with reductive gas.
The control and alarm of the operation of the limonite rotary kiln production system are controlled by PLC with few on-site operators.
Add a vertical preheater at the rotary kiln for limonite’s tail to make full use of preheating material, which greatly reduces fuel consumption.
It is easier to control the rotary kiln for limonite in the production process by using a progressive structure.
The heat is converted into hot flue by the cooler and sent back to the kiln, which greatly improves the thermal efficiency of the limonite rotary kiln.
